9. Plug distribution blower into the back of the electrical control center. 10. Connect the 28-gauge thermostat wire (not included) to the two (2) posts located on the side of the control center. For convenience, you might consider locating the wall thermostat next to your existing thermostat in your home. The thermostat MUST be installed for the furnace to operate. 11. Plug the 3-pronged grounded plug into a grounded electrical outlet. 12. With the connection of your chimney pipe and ductwork, your installation is complete.

Chimney Types and Recommendations See Diagram on page 9.

The chimney system is a critical element in the overall performance of the furnace. An improperly sized chimney, poor drafting chimney, unlined chimney, or chimney failure may result in unacceptable performance of the system, product failure, and/or fire and significant loss. Shelter strongly recommends the chimney system be professionally cleaned and inspected prior to installation. Check with local regulations to confirm whether or not inspection is required prior to installation. This furnace should only be connected to a clay-lined masonry chimney, masonry chimney with a properly installed SS 6” liner, or metal all-fuel Class A HT2100 chimney system. Refer to the installation instructions from the chimney manufacturer for proper installation methods and required clearances. Regardless of your chimney type, a minimum 6” diameter flue is required and at no time may the chimney be greater than 12” in diameter or exceed a .08 WCI of draft. The flue draft should be confirmed using a draft gauge or manometer. NEVER CONNECT THE FURNACE TO AN UNLINED CHIMNEY . We strongly recommend the installation of a 6” stainless steel liner for all systems to maintain a higher flue temperature which minimizes the accumulation of creosote and improves overall performance. The connection of the furnace to the existing chimney may be completed using a minimum of 24-gauge single wall black stove pipe or stainless-steel pipe. NEVER USE GALVANIZED PIPE WHICH WILL GENERATE DEADLY, POISONOUS GASES . The connection of the furnace to the chimney may never exceed a 60” (5’) horizontal run and must maintain a minimum rise of 2 inches per foot. Never install more than two (2) elbows when connecting to the existing chimney and the use of 45-degree elbows over one 90-degree elbow is recommended. For easy cleaning of the chimney system, install a clean-out “T” on the rear of the furnace and never operate the furnace without a cap installed on the clean-out access. All piping sections should be fastened together with the proper locking bands or a minimum of three (3) screws per section. The crimped or male end of all chimney sections should install pointing downward, towards the furnace, to form drip-free connections. 8
